1) 2x+3=9
The first step is to subtract 3 from each side,
2x =6
x=3
So
1) b
2) 3x -3 =15 The next step is to add 3 to isolate 3x
3x =18
x=6
2) d
3) -2p +9=-11 Subtract 9 from both sides so that we isolate the -2p
-2p=-11-9
-2p=-20
2p=20
p=10
3) a
4) 11=-4m -9 Add 9 from each side..
11 +9=-4m
20=-4m
-20=4m
m=-5
4)c
